I can't seem to declare a valid relationship in my application, but can do
so as a self-contained example.
the (working) example on the relevant columns is this:
class IpAddress(Base):
__tablename__ = 'ip_address'
id = Column(Integer, primary_key=True)
ip_address__cidr = Column(sqlalchemy.dialects.postgresql.CIDR,
nullable=False)
ip_range_id__primary = Column(Integer, ForeignKey("ip_range.id"),
nullable=True)
# _session = object_session(self)
ip_range__primary = relationship(
"IpRange",
primaryjoin="IpAddress.ip_range_id__primary==IpRange.id",
uselist=False,
)
ip_ranges_in = relationship(
"IpRange",
primaryjoin="IpAddress.ip_address__cidr.op('<<')(IpRange.ip_range__cidr)",
viewonly=True,
)
class IpRange(Base):
__tablename__ = 'ip_range'
id = Column(Integer, primary_key=True)
ip_range__cidr = Column(sqlalchemy.dialects.postgresql.CIDR,
nullable=False)
ip_addresses__primary = relationship(
"IpAddress",
primaryjoin="IpRange.id==IpAddress.ip_range_id__primary",
)
I can't create a valid `IpAddress.tracked_ip_ranges` relationship in my
application. It complains that it wants a foreign(), then a remote(), then
just fails.
Does anyone have tips on troubleshooting what is going on? something is
causing this to fail, but I can't figure out what.
